Given the following functions: f(x)=x^2

g(x)=x−3

Find the composition of the two functions and show your process:

f(g(x))

Step-by-step explanation:

Say you have a function . If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get When combining functions, you should do the same thing.

Here, we have We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). So, f(g(x)) would equal , which equals .

Hope this helps!

why can't you?

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
